An Adaptive Consensus Support Model for Group Decision-Making Problems in a Multigranular Fuzzy Linguistic Context
Mata, F.; Martinez, L.; Herrera-Viedma, Enrique (Article)Different consensus models for group decisionmaking (GDM) problems have been proposed in the literature. However, all of them consider the consensus reaching process a rigid or inflexible one because its behavior remains ... -
Aggregation of Unbalanced Fuzzy Linguistic Information in Group Decision Problems based on Type-1 OWA Operator.
Mata, F.; Perez, L. G.; Chiclana, Francisco; Herrera-Viedma, Enrique (Conference)Information aggregation is a key task in any group decision making problem. In the fuzzy linguistic context, when comparing two alternatives, it is usually assumed that assessments belong to linguistic term sets of ... -
Algorithms to Detect and Rectify Multiplicative and Ordinal Inconsistencies of Fuzzy Preference Relations
Xu, Yejun; Li, Mengqi; Cabrerizo, Francisco Javier; Chiclana, Francisco; Herrera-Viedma, Enrique (Article)Consistency, multiplicative and ordinal, of fuzzy preference relations (FPRs) is investigated. The geometric consistency index (GCI) approximated thresholds are extended to measure the degree of consistency for an FPR. For ... -
An alternative calculation of the consensus degree in group decision making problems
del Moral, Maria Jose; Chiclana, Francisco; Tapia Garcia, Juan Miguel; Herrera-Viedma, Enrique (Conference)In a problem of group decision-making it is desirable to obtain a solution with the highest possible degree of agreement –consensus- among the participants. For this aim, it is necessary to have tools that facilitate the ... -
An analysis of consensus approaches based on different concepts of coincidence
del Moral, Maria Jose; Tapia Garcia, Juan Miguel; Chiclana, Francisco; Al-Hmouz, A; Herrera-Viedma, Enrique (Article)Soft consensus is a relevant topic in group decision making problems. Soft consensus measures are utilized to reflect the different agreement degrees between the experts leading the consensus reaching process. This may ... -
An Analysis on Consensus Measures in Group Decision Making
del Moral, Maria Jose; Chiclana, Francisco; Tapia, Juan Miguel; Herrera-Viedma, Enrique (Conference)In Group Decision Making (GDM) problems before to obtain a solution a high level of consensus among experts is required. Consensus measures are usually built using similarity functions measuring how close experts’ opinions ... -

Analyzing highly cited papers in Intelligent Transportation Systems
Moral-Munoz, Jose Antonio; Cobo, M. J.; Chiclana, Francisco; Collop, Andy; Herrera-Viedma, Enrique (Article)Citation classics offer an outlook on those papers that have attracted great and historical interest by a research community and that could be also considered the basis of the research field. A new approach, which is called ... -
Are incomplete and self-confident preference relations better in multicriteria decision making? A simulation-based investigation
Dong, Yucheng; Liu, Wenqi; Chiclana, Francisco; Kou, Gang; Herrera-Viedma, Enrique; Herrera (Article)Incomplete preference relations and self-confident preference relations have been widely used in multicriteria decision-making problems. However, there is no strong evidence, in the current literature, to validate their ... -
Average-case consistency measurement and analysis of interval-valued reciprocal preference relations
Measuring consistency of preferences is very important in decision-making. This paper addresses this key issue for interval-valued reciprocal preference relations. Existing studies implement one of two di erent measures: ... -
A bibliometric analysis of the Intelligent transportation systems based on science mapping
In this paper we highlight the conceptual structure of the Intelligent Transportation Systems (ITS) research field in the period 1992-2011. To do that, an automatic approach for detecting and visualizing hidden themes and ... -
Challenges and Open Questions in Soft Consensus Models
Cabrerizo, F. J.; Chiclana, Francisco; Ureña, M. R.; Herrera-Viedma, Enrique (Conference)In group decision making problems, given the importance of obtaining an accepted solution by the whole group, the consensus has attained a great attention and it is virtually a major goal of these problems. Consensus, as ... -
Choice degrees in decision-making: A comparison between intuitionistic and fuzzy preference relations approaches
Chiclana, Francisco; Urena, Raquel; Herrera-Viedma, Enrique (Conference)Preference modelling based on Atanassov’s intuitionistic fuzzy sets are gaining increasing relevance in the field of group decision making as they provide experts with a flexible and simple tool to express their preferences ... -
A comparative analysis between two statistical deviation–based consensus measures in group decision making problems
Del Moral Avila, Maria Jose; Chiclana, Francisco; Tapia Garcia, Juan Miguel; Tapia Garcia, Cristobal; Herrera-Viedma, Enrique (Conference)The mean absolute deviation and the standard deviation, two statistical measures commonly used in quantifying variability, may become an interesting tool when defining consensus measures. Two consensus indexes which obtain ... -
A Comparative Study on Consensus Measures in Group Decision Making
del Moral, Maria Jose; Chiclana, Francisco; Tapia Garcia, Juan Miguel; Herrera-Viedma, Enrique (Article)In group decision making problems it is desirable to obtain a high level of consensus among experts before reaching a solution. It is customary to construct consensus measures by using similarity functions to quantify the ...
